Prince William and Kate Middleton gave the world a glimpse of their new son, the tiny future regent born amid much fanfare in London Monday.

Outside St. Mary's Hospital, where 31 years ago Prince Charles in a pin-striped suit, and Princess Diana in a polka-dot maternity smock, showed off their firstborn son, William and Middleton posed for photos with the baby and spoke briefly to the press.

"Well, he has a good pair of lungs on him, that's for sure," Prince William, before joking about the baby's wispy hair. "He's got way more than me." He also said they are "still working on a name."

The couple was visited earlier today by Prince Charles and his wife Camilla, and Middleton's parents, Carole and Michael Middleton. Carole Middleton called her grandson "absolutely beautiful," and said he and his mother were "doing really well." The couple returned to Kensington Palace after showing off the baby.

Middleton was forced to reveal her pregnancy earlier than expected after she was hospitalized for severe morning sickness, but the rest of her pregnancy and the birth were apparently without complications.

Though the couple never revealed their due date, the press had been camped outside the hospital since July 1, but Middleton didn't go into labor until Monday morning. She delivered the 8-pound, 6-ounce baby at 4:24 p.m.

"I'll remind him of his tardiness when he's a bit older because I know how long you've all been sat out here," Prince William told the reporters. "Hopefully the hospital and you guys can all go back to normal now and we're going to look after him."

The Prince of Cambridge is third in line for the British throne, after Prince Charles and Prince William, and if he follows their reigns, will be the 43rd regent since William the Conqueror.
